;	Change the edit history, retroactive to last release.
;	Include date, initials, and expand the SPR number to
;	show if it is a TOPS-10 or TOPS-20 SPR. Also use

;	that edits were made after 2B was released.

;112	PY	10-Sep-81	SPR 10-31533
;	Fix problem with line sequence numbers so that the optional

	FORMAT OF TRACE BLOCK    (LINK ITEM TYPE 1060)


THE LINK ITEM TYPE, "TRACE BLOCK DATA" IS USED TO INCLUDE IN
THE REL FILE INFORMATION THAT CAN BE USED TO BOTH VERIFY AND CHANGE
THE PATCH STATUS OF A PROGRAM. THE FORMAT OF THE TRACE BLOCK FOLLOWS:


THE FIRST PART OF THE TRACE BLOCK IS THE STATIC AREA. THIS AREA APPEARS
IN EACH MODULE THAT IS AFFECTED BY THE PARTICULAR EDIT. THE STATIC AREAS
GIVE INFORMATION COMMON TO ALL MODULES AFFECTED BY AN EDIT AND
THE VARIABLE AREA GIVES THE CHANGING DATA ON THE
PARTICULAR EDIT AS IT GOES FROM MODULE TO MODULE.

	!=====================================!
TB$HED	! LINK ITEM NUMBER ! LENGTH OF BLOCK  !
	!-------------------------------------!
TB$EDT	!   SIXBIT EDIT NAME (UP TO 6 CHRS)   !
	!-------------------------------------!
TB$STA	!   -1 IF ACTIVE   !WHO LAST AFFECTED !
	!-------------------------------------!
TB$MAK	!   WHO CREATED    !  DATE (15 BIT)   !
	!-------------------------------------!
TB$INS	!  WHO INSTALLED   !  DATE (15 BIT)   !
	!-------------------------------------!
TB$FUT	!       RESERVED FOR FUTURE USE       !
	!-------------------------------------!
TB$LEN	! # OF ASS. EDITS  !  # OF PCO GROUPS !
	!=====================================!



	THE STATIC AREA, WHICH IS REPEATED IN EACH MODULE, IS FOLLOWED
BY A VARIABLE AREA. THE VARIABLE AREA CONSISTS OF TWO PARTS, THE
FIRST GIVING DATA ON THE ASSOCIATED EDIT STATUS FOR THIS MODULE AND
THE NEXT GIVING THE ACTUAL PROGRAM CHANGE ORDERS (PCO'S). THE
LENGTH OF EACH OF THESE AREAS APPEARS IN THE STATIC AREA OF THE TRACE 
BLOCK.

          FOR EACH ASSOCIATED EDIT, THE FOLLOWING GROUP APPEARS:

	!=====================================!
TB$AEN	!      SIXBIT EDIT NAME OF A.E.       !
	!-------------------------------------!
TB$AES	!X!        RESERVED FOR FUTURE        ! X=0 IF MUST NOT BE PRESENT
	!=====================================!  =1 IF MUST BE PRESENT

	AFTER THE ASSOCIATED EDIT GROUPS APPEAR, IF THERE ARE ANY, THE
PCO GROUPS FOR THAT MODULE APPEAR. THERE ARE CURRENTLY THREE TYPES
OF PCO GROUPS;  INSERT,REMOVE AND RE-INSERT. THEY CAN
APPEAR IN ANY ORDER AND THE TOTAL NUMBER IS OF COURSE VARIABLE.

		INSERT PCO:
	!=====================================!
TB$PCO	!PCO TYPE CODE (1) ! LENGTH OF GROUP  !
	!-------------------------------------!
TB$DAT	!    INSTRS  INSRTD! ADDR. OF INSERT  ! 
	!-------------------------------------!
TB$PAT	!  NEW ADDR OF ORG !  ADDR OF PAT CODE!
	!=====================================!


		REMOVE PCO:
	!=====================================!
TB$PCO	!PCO TYPE CODE (2) ! LENGTH OF GROUP  !
	!-------------------------------------!
TB$REN	!          SIXBIT EDIT NAME           !
	!=====================================!
	
	
		RE-INSERT PCO:
	!=====================================!
TB$PCO	!PCO TYPE CODE (3) ! LENGTH OF GROUP  !
	!-------------------------------------!
TB$RIN	!          SIXBIT EDIT NAME           !
	!=====================================!


		ALTER PCO:
	!=====================================!
TB$PCO	!PCO TYPE CODE (4) ! LENGTH OF GROUP  !
	!-------------------------------------!
TB$DAT	!      UNUSED      ! ADDR. OF INSERT  ! 
	!-------------------------------------!

SUBTTL ROUTINES TO INDEX THE LIBRARY

COMMENT	*	THE INDEXING OF LIBRARY FILES IS DONE IN TWO PASSES.
	ON PASS 1 THE LIBRARY FILE IS COPIED AND ALL ENTRIES STORED
	IN CORE ALLONG WITH A POINTER TO THE BEGINING OF THE BLOCK.
	A DUMMY INDEX BLOCK (TYPE 14) IS OUTPUT AT THE BEGINING OF THE
	NEW LIBRARY AND ONE IS OUTPUT WHENEVER THE CURRENT INDEX BLOCK
	FILLS A BUFFER.
	ON PASS 2 THE DUMMY INDEX BLOCKS ARE REPLACED BY REAL ONES.
	MAKLIB USED USETO'S AND DUMP MODE.
	IF THE OUTPUT DEVICE IS DTA MAKLIB USES UGETF UUO'S TO FIND
	THE NEXT BLOCK AND NON-STANDARD DUMP MODE TO WRITE THE INDICES.

SUBTTL DESCRIPTION OF INTERIM SYMBOL TABLE (IST)

COMMENT \

	THE INTERIM SYMBOL TABLE (IST) CONTAINS PAIRS OF WORDS
THAT DESCRIBE ACTIONS TO BE TAKEN FOR FIXING UP FORWARD REFERENCES TO
SYMBOLS, EXTERNALS AND LITERALS.
THE IST IS ALSO USED FOR ASCII,ASCIZ AND SIXBIT STRINGS THAT
EXTEND FOR MORE THAN ONE WORD.


WHEN EVAL FINDS A SYMBOL THAT IS UNDEFINED:

1) SET OPERAND RESULT (AC A) TO 0
2) SET SYMBOL FIXUP POINTER (AC C) TO BE POINTER TO ENTRY IN IST
3) SET IST WORD 1 TO BE SIXBIT THIS SYMBOL NAME
4) SET 2ND WORD OF IST PAIR TO IS.UDF, ALSO IS.DER IFF SYMBOL FOLLOWED BY ##
	ALSO, RELOC IS CLEARED IF EXTERNAL.
5) THE RELOC AND SYMBOL FIXUP ARE CARRIED THRU ALL LATER OPERATIONS
6) AT THE END OF EVAL, THE RH OF IST ENTRY WORD 2 IS REVERSED TO POINT
  BACK AT THE LOCATION THAT CODE WORD IS STORED IN. 
8) WHEN SYMBOL IS RESOLVED, ITS VALUE IS STORED INTO THE APPROPRIATE
  HALF OF THE WORD.


WHEN EVAL FINDS A REFERENCE TO AN EXTERNAL:
 
1) RESULT,RELOCATABILTY ARE SET TO 0.
2) SYMFIX (AC C ) IS SET TO POINT TO FIRST FREE IST PAIR
3) WORD 1 OF PAIR GETS SIXBIT SYMBOL NAME
4) WORD 2 GETS FLAG OF IS.DER (DEFFERED EXTERNAL REFERENCE)
5) OPERAND IS CARRIED THRU LATER OPERATIONS
6) AT END OF EVAL, POINTER IS REVERSED TO INDICATE FIXUP ADDRESS
7) IF ALL GOES WELL, A SYMBOL TABLE ENTRY IS MADE LATER TO HOOK
   REQUEST INTO GLOBAL CHAIN.


 WHEN EVAL FINDS A REFERENCE TO AN LITERAL:

1) THE EXPRESSION WITHIN BRACKETS IS EVALUATED.
    A LINKED LIST OF WORDS IS FORMED FOR THE LITERAL.
1A) THE EXPRESSION RESULT,ITS RELOC AND SYMFIX ARE STORED IN
	FREE CORE AS A LINKED LIST

2) A POINTER TO THE LINKED LIST IS PUT INTO THE FIRST WORD OF THE IST PAIR
4)  RESULT IS SET TO 0, RELOC TO RH ONLY (1), SYMFIX (AC C) IS SET TO
    POINT BACK AT THE IST PAIR. FLAG (AC D) IS SET TO C.LIT
5)  THE OPERAND IS PASSED BACK FOR FURTHER USE.
6)  AT THE END, THE LITERAL WORD IS TO BE INSERTED WITH APPROPRIATE
    RELOCATION AND THEN THE POINTER IS USED TO DUE THE NORMAL FIXUP.


WHEN EVAL FINDS THAT A STRING EXTENDS FOR MORE THAN ONE WORD:

1) THE FIRST WORD OF THE STRING IS LEFT ALONE
2) AN IST PAIR ENTRY IS MADE. THE FIRST WORD IS:
	XWD -COUNT OF WORDS, ADDRESS OF STRING
3) THE EXCESS WORDS ARE GENERATED INTO FREE CORE (THAT WORD 1 OF IST PAIR
	POINTS TO)
4) THE USUAL STUFF IS DONE WITH IST POINTER CARRIED AROUND BY THE
	EXPRESSION AND REVERSED AT EXIT FROM EVAL.
	THE SECOND WORD OF THE IST IS THEN:  IS.MWS,,ADDRESS 1ST WORD GENERATED INTO
5) AT FIXUP TIME, THE STRING IS GENERATED.

COMMENT  \

THIS ROUTINE IS A RECURSIVE MACRO STATMENT EVALUATOR
WHICH IS CALLED WHENEVER :

1) THERE IS A PRIMARY STATEMENT (IE JUST LEFT LABEL FIELD)
2) A LEFT BRACKET 74  WAS SEEN
3) A LEFT PARENTHESIS WAS SEEN "("
4) A LEFT BRACKET WAS  SEEN "["

THE CURRENT STATE IS SAVED ON ENTRY, AS REFLECTED BY THE
ACS %F,%V,%R,%S. THE RESULT IS RETURNED ON EXIT IN THE MEMORY LOCATIONS
R%F,R%V,R%R,R%S.

USAGE:	%V	CONTAINS THE VALUE OF THE STATEMENT
	%R	CONTAINS IN EACH HALF THE MULTIPLIER OF RELOC CONSTANT
		WHICH CAN BE EITHER 0 OR 1
	%S	CONTAINS IN EACH HALF EITHER 0 OR THE ADDRESS OF A 
		TWO WORD ENTRY IN THE IST FOR FIXING UP FORWARD REFERENCES
	%F	CONTAINS FLAGS INDICATING OUR POSITION
		IN THE MACRO-10 STATEMENT.


EVALUATION OF THE MACRO-10 EXPRESSIONS IS DONE USING A TWO STACK
PRECEDENCE GRAMMAR EVALUATOR. ONE STACK CONTAINS THE OPERANDS
AND THE OTHER CONTAINS THE OPERATORS.
EACH OPERAND ENTRY CONTAINS 4 WORDS,SIMILIAR
IN USE TO THE ACS %F,%V,%R,AND %S. THESE ARE COMBINED
TO FORM LARGER EXPRESSIONS AND FINALLY A FULL MACRO-10 STATEMENT.

; PSEUDO-OPERATOR TABLE FOR THE MACRO EVALUATOR.
; THIS TABLE CONTAINS THE NAMES,CHARACTERISTICS AND THE ADDRESS
; OF THE PROCESSOR FOR EACH OF THE MACRO PSEUDO-OPS. THESE PSEUDO
; OPS ARE HANDLED AT THE LEVEL OF PRIMARY CELL, WHEN MACSRC
; FINDS THAT THE SYMBOL IT IS SEARCHING ON
; IS IN THIS TABLE.
;
; THERE ARE CURRENTLY THREE CHARACTERISTICS FOR PSEUDO-OPS
; 
; 1) $INP - DONT FIND THIS PSEUDO-OP IF NOT PRIMARY STATEMENT
	; THIS MEANS PRETEND ITS NOT FOUND IF WE HAVE:
	;    ['PSEUDO-OP' ...]
	;    ('P.O.'...)
	;    <'P.O.'...>
      ;IN OTHER WORDS, ANY CASE BUT  :
	;  LABEL:   PSEUDO-OP ....
	;OR     PSEUDO-OP.....

;	2) $III -  MEANS IF THIS PSEUDO-OP IS FOUND INSIDE THE RANGE
;	   OF '.INSERT' .......  '.ENDI' THEN ITS A FATAL ERROR.

; 3) $COF - BEFORE RETURNING FROM EXECUTING PSEUDO-OP, CLEAR
;	    THE BIT THAT SAYS WE ARE IN THE OP CODE FIELD OF THE
;	    CURRENT STATEMENT. THIS IS USED FOR PSEUDO-OPS
;	    THAT "EAT" THE REST OF THE LINE, BUT WISH TO
;	    USE EVALEX TO DO EXPRESSION EVALUATION. TURNING OFF
;	    THE I.OP FLAG MEANS THAT EXPRESSIONS INVOLVING LABELS THAT
;	     ARE THE SAME AS BUILT IN SYMBOLS, WILL GET EVALUATED RIGHT.
